[Termes IGN] International Terrestrial Reference FrameRésumé : (auteur) The EUREF key infrastructures are the EUREF Permanent GNSS Network (EPN) and the Unified European Levelling Network (UELN). The EPN runs almost 250 Global Navigation Satellite System (GNSS) stations in a well organized environment and serves as the backbone of the realization of and access to the European Terrestrial Reference System (ETRS89) and as contribution to the densification of the International Terrestrial Reference Frame (ITRF2008). The upcoming European navigation system Galileo will be a big challenge for the EPN in sense of upgrading the station network. Almost half of the EPN stations are capable of streaming their data in real-time. To strengthen the robustness of the real-time data and product distribution two additional Ntrip broadcasters were set up at different premises in Europe. The EVRS and the ETRS89 have been adopted by the European Community as coordinate reference systems in INSPIRE for environmental policies, or policies and activities that have an impact on the environment.

[Termes IGN] orbitographieRésumé : (Auteur) The realisation and maintenance of a Galileo Terrestrial Reference Frame (GTRF) is the main function of the Galileo Geodetic Service Provider (GGSP). The GTRF shall be compatible with the latest International Terrestrial Reference Frame (ITRF) within a precision level of 3 cm (2 sigma). The connection to the ITRF is realized and validated by stations of the International GNSS Service (IGS) and by geodetic local ties to stations equipped with other geodetic techniques. It is demonstrated that this GTRF can be maintained by including the Galileo Signal-in-Space data, once Galileo reaches its operational stage.
The GGSP will also provide additional products, such as Earth Rotation Parameters, satellites orbits, clock corrections for satellites and stations, which will be offered to the Galileo user community to have most precise access to the GTRF and will be used to monitor the accuracy of the corresponding Galileo Mission Segment.
The GGSP was built up in time, and for a final demonstration the full system was operated for an interval of 6 months. During that time also microwave data from the two active GIOVE satellites were used.
The GGSP Consortium followed the most up to date IGS standards of weekly processing during seven monthly campaigns (November 2006 to June 2008) and a continuous processing from September 2008 to February 2009 delivering several versions of the GTRF. The latest GTRF solution (GTRF09v01) has an RMS position difference with respect to the ITRF2005 computed over the 71 common stations of 1.1 and 2.9 mm in the horizontal and vertical components, respectively. The RMS velocity differences are 0.3 and 0.6 mm/y, respectively. The GGSP GPS satellite orbits and clock corrections agree with the IGS Final products at a level of 5–11 mm and 0.02–0.03 ns, respectively.Numéro de notice : A2011-588 Affiliation des auteurs : LAREG+Ext (1991-2011) Thématique : POSITIONNEMENT Nature : Article nature-HAL : ArtAvecCL-RevueIntern DOI : 10.1016/j.asr.2010.02.001 Date de publication en ligne : 06/02/2010 En ligne : https://doi.org/10.1016/j.asr.2010.02.001 Format de la ressource électronique : URL article Permalink : https://documentation.ensg.eu/index.php?lvl=notice_display&id=90663

[Termes IGN] traitement de données GNSSRésumé : (Auteur) Starting in 2001 the EUREF Permanent Network (EPN) Local Analysis Centres (LAC) are delivering Zenith Total Delay (ZTD) parameters which were combined at the BKG (Bundesamt für Kartographie und Geodäsie, Germany) combination facility. The results have been step-by-step improved, depending on several changes of the processing scheme, leading to an internal precision of 2-3 mm ZTD. The availability of a set of homogeneously processed GPS satellite orbits, clocks and Earth Rotation Parameters (ERP) covering a period of more than a decade (the so-called Potsdam-Dresden reprocessing) motivated MUT (Military University of Technology, Poland) to the all-in-one processing of the EPN stations for the same period. The applied strategy thereby followed the guidelines for EPN processing. While the improvement in coordinate estimation has been recently demonstrated, this paper investigates the quality of the ZTD parameters estimated together with the coordinates. Comparisons with the existing EUREF combined solution, with IGS solutions and with radiosonde data will be presented to evaluate the possible improvement in ZTD estimation by reprocessing activities.

First the GPS observables used within this paper are descri-bed and the mean problems concerning with kinematic use of GPS like ambiguity resolution, cycle slips and multipath are pointed out. To adjust the ambiguities in a fast and efficient way a Kalman filter algorithm is presented. The results of the integrated system using different types of vehicles are described. Finally it is shown that by using the observations of all available antennas the accuracy for attitude calculation is the highest one.
